CASTELL GRIND ROUTES

 The Full Grind, a 62-mile figure-eight counterclockwise course, winds through the Texas Hill Country with a south loop around House Mountain and a north loop, intersecting at Castell’s midpoint. The town serves as a vital refueling hub for riders continuing the 62-mile journey, with a noon cutoff determining who can proceed to the north loop. Starting and ending with some of the Hill Country’s finest gravel, the route kicks off the south loop with Keyserville Road—a grueling 9-mile gradual climb that tests your endurance and tire choices, leaving an unforgettable mark. The final 15 miles of the north loop deliver relentless, rugged gravel, demanding skill and stamina. Recommended for intermediate to advanced cyclists with strong fitness and gravel experience, the Full Grind is the ultimate Hill Country challenge.
